Haiti

I am planning to donate money to the earthquake relief effort in Haiti. As usual I want to make sure the money is actually used promptly and through the right channels. Any thoughts on which organization it would be best to donate to? Candidates include Partners in Health, the American Red Cross, Doctors without Borders, the White House and musician Wyclef Jean (in many of these cases you can simply donate by texting; the amount will be added to your mobile phone bill)
